The Questionnaire for Lung Transplant Patients was designed for clinical use by the pulmonary transplant team in the routine evaluation of lung transplant recipients. Using the self-administered questionnaire, recipients check symptoms that they have had since their last evaluation and rate their shortness of breath, cough, and activity tolerance.
To determine whether the questionnaire meets reliability and validity standards for empirical measurement.
Demographics and disease-severity characteristics were examined in a cross-sectional survey of 37 recipients. Test-retest and intraclass correlation methods were used to estimate stability, and the Cronbach alpha was used to estimate internal consistency. Criterion validity was examined by using The Modified Symptom Frequency/Symptom Distress Scale, Functional Performance Inventory, and visual analog scales for cough and shortness of breath as criterion measures. Construct validity was examined to assess the predicted negative correlation between symptoms and functional performance.
The questionnaire and its subscales were internally consistent (Cronbach alpha = 0.82, 0.76, 0.80, and 0.96), and the questionnaire was stable (r = 0.70) and reliable (intraclass correlations = 0.80 and 0.90). Significant correlations were found between the questionnaire and all criterion measures (r = 0.50-0.93). Significant correlations in the predicted negative direction were found between the respiratory subscale and functional performance (r = -0.51) and between cough (r = -0.51) and shortness of breath (r = -0.68) ratings and functional performance.
The Questionnaire for Lung Transplant Patients is reliable and valid, and it provides scientifically sound information for clinical and empirical evaluation of symptoms and their effects on activity tolerance after lung transplantation.
肺移植患者问卷是由肺移植团队设计，用于在肺移植受者的常规评估中进行临床使用。通过自行填写问卷，受者勾选自上次评估以来出现的症状，并对其呼吸急促、咳嗽和活动耐量进行评分。
确定该问卷是否符合实证测量的信度和效度标准。
在对37名受者的横断面调查中检查人口统计学和疾病严重程度特征。采用重测法和组内相关方法估计稳定性，使用克朗巴哈系数估计内部一致性。通过使用改良症状频率/症状困扰量表、功能表现量表以及咳嗽和呼吸急促的视觉模拟量表作为标准测量来检验效标效度。检验结构效度以评估症状与功能表现之间预测的负相关。
问卷及其子量表具有内部一致性（克朗巴哈系数分别为0.82、0.76、0.80和0.96），问卷具有稳定性（r = 0.70）和可靠性（组内相关系数分别为0.80和0.90）。问卷与所有标准测量之间均发现显著相关性（r = 0.50 - 0.93）。在呼吸子量表与功能表现之间（r = -0.51）以及咳嗽评分（r = -0.51）和呼吸急促评分（r = -0.68）与功能表现之间均发现了预测的负向显著相关性。
肺移植患者问卷可靠且有效，它为肺移植后症状及其对活动耐量影响的临床和实证评估提供了科学合理的信息。
